My evo blew up a week after Undercover Performance tune.
If it was on 93 octane, 28psi should have been fine as long as timing was good. Your power numbers don't reflect an unsafe tune. If it had too much timing at 28psi it would have probably about 10% more power.
I would have to side with the tuner on this and that it was likely the blocks fault, and not the tune. 280wtq is not going to take out a rod. At that power level, detonation would just melt the piston, and it would likely just quit before you windowed the block..

Well i was just happy that im finally driving my car thats all lol, I thought 3 gear pull wouldnt cause that much damage since i did them before. But sh*t happens i guess haha
The car didnt really have any major problem other than maintenance and runs so lean and just not right cuz no tune, so i stoped driving it till the tune and then that happened after the tune
My stock motor and turbo was tuned at 32 psi no problem and was making 500/380, something else happened most likely you was only making 296/279 that is nothing at all just a little above stock number so i would have to guess something was wrong with that motor and that is one reason why the guy sold car car he probably knew something was not right and handed it off to you.
Stock turbo and 500hp? Hmm...
OP a lot of this doesn't add up. 28psi and such low power, You "making a pull" when you think the car isn't right, your side of what all the tuner said/did, etc.
I don't think we're getting the whole story. Either way, something was wrong with the car that isn't the tuner's fault. I think this is an unfortunate instance of a seller cheating the buyer.

Usually I'm all for customer protection, but you have a lot of variables without data. It's difficult to place blame as a result.
I think the best bet is pulling your tune off, listing your mods and having an expert evo tuner take a look at it for any red flags. Just because boost is high, doesn't mean the tune was bad.
What kind of diverter valve do you have? If stock, they aren't known to hold more than 26psi consistently. Also, I've seen boost gauges read high, what one do you have?
Then there is atmosphere it was tuned in, what timing was like, what the fuel in the car was like.
The integrity of the drive train seems very suspect to me. Did you have the car inspected before you bought it?

anyway, it still seems there is something more going on here. i think you car had a hardware issue that was ultimately the downfall. since you bought the car as-is, it's time to move on and get her running again.
the tune doesn't seem to have anything to do with the car dying. it may have helped, but not the fault.

Yea everything was pretty good just needed some maintenance
as long as it was low enough that you were able to budget for an engine, you are good. i've done that before. my current car had low compression in a cylinder and a dead clutch. i got it for a price i was okay with after repairing these items.

I know the guys at Undercover very well, I'm actually good friends with the owners and talk with them frequently. I know Garth to be a one of the most knowledgable tuners on this side of the US. He has tuned DOZENS if not hundreds of GT-R's at this point, definitely hundreds of Evo's and STI's as well. I've gone over his work actually and I can vouch for it 100%. I highly doubt it was Garth's fault that anything happened to your motor. He's not known to go razor's edge on a setup like yours. That Mustang dyno is notoriously low reading(I used to own it so I know firsthand on that) so your numbers were right in line with what they should have been.
I know it sucks ending up with a blown motor, but if the tune was as bad as you're thinking, it would have blown up on the dyno. Not trying to knock your credibility or anything, but I've known these guys for years, have done business with them, and trust them enough to let them do work on all of my cars. S*** happens, but I'd definitely like to see the tune before passing judgment.

Everybody makes mistakes, the big mistake is to try to blame it on others.
I have no problem at all to go over the tune tonight if u wanna do it, but let me know before i get my car re-tuned.

I know they work on gtrs and worked on alot of cars and all this stuff. But their reaction, or not trying to te responsibility for what happened and tried to blame it all on me is what concerns me, the tuner who knows everything about the car shouldn't raise boost like that without even me knowing or asking for it.

Outside of that though, you had a lot of unknown variables and regardless of whether they raised the boost or not, that's a hard fact. I'd have to talk to those guys to find out exactly what happened, but sounds like they had knowledge of the car prior to your purchase. Still, certain things like boost, timing, and fuel are going to be adjusted when they tune vehicles; any tuner would do the same regardless of where you go. I find it difficult to believe that Garth didn't tell you how much boost you were running when you picked the car up. He's one of the most thorough guys on the planet and I doubt other shops would be flying him out to other states if he was so absent-minded.
I'm local so I'd definitely like to check it out.
